Determining a Midday Stem Water Potential Threshold for Irrigation of Table Grapes Water potential threshold

Publikováno v: South African Journal of Enology and Viticulture. 43

Sustainable table grape production depends on efficient water supply. Water potential is a useful indicator of water constraints in grapevines. In this regard, midday stem water potential (ΨS) is considered to be a better indicator of grapevine wate

An Assessment of Treated Municipal Wastewater Used for Irrigation of Grapevines with Respect to Water Quality and Nutrient Load Assessment of TMW for vineyard irrigation

Autor: C. L. Howell, K. Hoogendijk, P.A. Myburgh, E. L. Lategan

Publikováno v: South African Journal of Enology and Viticulture. 43

The impact of treated municipal wastewater (TMW) irrigation on soil and grapevines was assessed under field conditions in vineyards in the Coastal region of South Africa. Grapevines were irrigated using TMW from the City of Cape Town uninterruptedly

Selection of Grass and Broadleaf Crops as Catch Crops where Winery Wastewater is Used for Irrigation: A Review

Autor: C. L. Howell, J. C. Fourie, N. Masekwana

Publikováno v: South African Journal of Enology and Viticulture, Volume: 42, Issue: 1, Pages: 10-18, Published: 2021

Winery wastewater contains high levels of elements such as sodium, phosphorus, potassium, as well as chemical oxygen demand, sodium adsorption ratio and pH. This may raise concerns regarding the pollution of the surrounding environment. Environmental

Effect of sucrose phosphate and sorbitol on infectivity of enveloped viruses during storage

Autor: M J Miller, C L Howell

Publikováno v: Journal of Clinical Microbiology. 18:658-662

Cytomegalovirus and varicella-zoster virus recovery from sucrose phosphate (0.2 M SP) and 70% sorbitol (sorbitol) was compared after storage at -70, 4, and 20 degrees C over time. Recovery from 0.2 M SP was uniformly better. More tissue culture infec

Rapid detection and identification of herpes simplex virus in cell culture by a direct immunoperoxidase staining procedure

Autor: C L Howell, M J Miller

Publikováno v: Journal of Clinical Microbiology. 18:550-553

Cell monolayers were inoculated with 169 fresh and 76 previously frozen clinical specimens and examined for the presence of herpes simplex virus (HSV) by noting the appearance of characteristic cytopathic effect (CPE) and by using direct immunoperoxi

Comparison of rates of virus isolation from leukocyte populations separated from blood by conventional and Ficoll-Paque/Macrodex methods

Autor: M J Miller, C L Howell, W J Martin

Publikováno v: Journal of clinical microbiology. 10(4)

One hundred fifty-two blood specimens, largely from immunocompromised patients, were collected in heparinized Vacutainer tubes and divided into paired aliquots of equal volume. Buffy-coat preparations, containing mixed leukocyte and separate mononucl

Elimination of toxicity and enhanced cytomegalovirus detection in cell cultures inoculated with semen from patients with acquired immunodeficiency syndrome

Autor: C L Howell, M J Miller, D A Bruckner

Although semen is a particularly rich source of cytomegalovirus (CMV) and is useful for monitoring CMV shedding, its culturing is associated with extensive monolayer toxicity, isolation failures, and lengthy detection times. Inoculation of fractionat

Efficacy of ozone in eradication of Legionella pneumophila from hospital plumbing fixtures

Autor: C L Howell, R. L. Kreiling, R. E. Whittaker, Paul H. Edelstein

The effect of ozonation of supply water for one wing of an unoccupied hospital building which had positive cultures for Legionella pneumophila from multiple potable water fixtures was studied in a prospective, controlled fashion. Mean ozone residual
